KEROSENE-TORCH.

Application filed August 15, 1914, Serial No. 856,919. Renewed January 6, 1917.

it) all whom it may concern:

Be it known that I, ARTHUR E. HAUCK, a citizen oithe United States, and a resident of the city and State of New York, county of Ki; borough of Brooklyn, and whose post address is No. 1&0 Livingston street, E-rooklyn, have invented a new and useful Improvement in Kerosene-Torches, of which the following is a specification.

The abject of my invention is to provide atorch which is especially adapted tmkero sene, although it may be used with gasolens or alcohol, if desired. Heretofore, when gasolene or alcohol has been used in a torch, there has been danger of an explosion, and the liquid employed is exceedingly inflammable, and therefore likely to give trouble. Kerosene contains more heat units than either gasolene or alcohol, and is much cheaper, but it is diflicult to ignite and keep ignited, so that it will burn without smoke. The object or" m invention is to provide a torchv in which rosene can be used without smoke, and without trouble, and in which kerosene may be lighted more easily than gasolene or alcohol can be lighted in an ordinary torch. This and other objects my invention, one embodiment of which is hereinafter set forth. For a more particular description of my invention, reference is to be had to the ac companying drawings, forming a part hereof, in which Figure 1. is a view of the burner top of my improved torch, parts being shew n in cross-section.

Fig. 5 is an enlarged sectional view of a portion of the front of the burner, taxen on the line 3--3. of Fig. 1.

Throughout the various views of the drawings similar reference characters designate similar parts. I

My improved torch has a tank 1 of the conventional kind, in which is mounted the usual pump 2, in the customary manner. Also near. the bottom of this tank 1 runs the usual upwardly-extending pipe 3 to the top of the tank so that the liquid at the bot- Specification of Letters Patent.

tom of the tank is forced by the air resting thereon upwardly through this pipe 8,thence by a check-valve 4- to the passages in the burner 6, and from thence to the atomizer 5, from which the oil, or other fuel may be atomized and blown into the burner 6, in the conventional 'manner. I

The bottom of the burner 6 is made'solid, except for passages 7 and 8, which run in converging paths to an opening closed by a screw-plug 9. The passage 8 connects with the check-valve 4, and the passage 7 runs to the atomizer 5.

The screw-plug 9, which closes the forward ends of the passages 7 and 8, is provided with a swivel 10, in which is carried a V-wire 11. The function of this wire is to rest in the passages 7 and 8, and force the liquid in the same into a space between the wire and the bottom of the burner 6, so that the incoming-kerosene, or other fuel, will be thoroughly vaporized by the burner 6 before reaching the atomizer 5. As the screw-plug 9 can be readily removed, it is obvious that the passages 7 and 8 and the wire 11 can be readily cleaned.

The atomizer 5 has a passage 12 of the conventional kind running from the bottom of the burner 6 to the needle-valve 13, which is mounted in the usual way. This atomizer also has an auxiliary nozzle 14: placed over its forward end; that is, the end next the burner 6, and separated slightly therefrom, and this auxiliary nozzle 14 is connected by a tube 15 to a needle-valve 16 mounted in the top of the tank 1, so that air may pass through the gassage 15 whenthe valve 16 is opened su ciently to permit this. This valve 16 may be used as a regulating valve, so as to admit; more or less air to the torch when the same is use, whereby the temperature of the flame issuing from the burner may be varied, and it also serves to supply air to the oil vapor issuing from the needle valve 18 before the burner 6 is heated so that this oil is thoroughly atomized,

" and while so atomized and mixed with air,

it may be readily ignited :without smoke. To facilitate this operation a small cup 17, provided with asbestos, or other suitable material, is placed right below the nozzle 14, as shown, and the leakage in this cup, when the needle-valve 13 is first opened will constitute a sufficient supply of the oil on the asbestos to be readily lighted, and then when ciently the valve 16 is opened and the fuel through the valve 13 is thereby thoroughly sprayed, the flame from the pilot cup 17 will light the atomized and aerated fuel, and thereby cause the same to heat the burner 6. This heating takes place without any smoke whatsoever and soon the burner 6 is sufliheated to thoroughly vaporize the fuel passing by the wire 11 in the passages 7 and 8, and then the valve 16 may be closed tight, or, if an intensely hot flame is desired, the valve 16 will be more or less open, in which event the pump will have to be operated more frequently.

It will be noted that the extreme end of the burner 6 is not only coned to reduce the area of its part near the flame, but it is also slotted, as shown at 18, so as to permit more air to mingle with the flame prior to its issuing from the burner, as I have found by so doing a hotter flame may be produced with the same oil consumption.

In view of the foregoing, the operation of my improved torch will be readily understood. Assuming that the tank 1 has a suitable amount of oil in it, and the operator desires to use this torch, he first opens the needle-valve 13 of the atomizer 5, and permits a little oil to leak into the pilot cup 17.. He then lights the oil in thiscup 17 and then opens the valve 16 so that the oil issuing from the nozzle 14: will be thoroughly atomized and aerated while in a vaporous state. This atomized and aerated oil burns without smoke and in a few seconds the torch 6 is so hot that the valve 16 may be closed, and the intensity of the flame regulated by the valve 13 in the atomizer 5, although if desired as above stated, the heat may be intensified by admitting additional air through the valve 16. When the operator is through with the torch, he closes both the valves 13and 16if the valve 16 is openand then the flame is extinguished immediately.

While I have shown and described one embodiment of my invention, it is obvious-that it is not restricted thereby, as it is broad enough to cover all structures that come within the scope of the annexed claims.

What I claim is:--

1. In a device of the class described, a burner with a slotted and coned end at the flame edge of said burner.

2. In a device of the class described, a burner tube having a bottom Wall with passages therein running to a common opening, and a screw-plug closing said opening.

3. In a deviceof the class described, a burner tube, passages in the bottom wall of said burner running to a common opening, and a removable wire resting in said passages.

4. In a device of the class described, converging passages running to a common opening, a removable wire resting in said passages removable through said opening and means for closing said opening.

5. In a device of the class described, a burner with converging 1 passages therein, and a screw-plug with a wire attached thereto, said wire extending into said passages, whereby fuel passing through said passages is forced against the walls of the passages.

6. In a torch of the class described,-'a fuel tank, a ipe running below the top of the fuel leve in said tank, a burner connected to said pipe, an atomizer connected to said burner and to the top of said tank, an auxiliary nozzle on said atomizer, and a pilot cup adjacent to said auxiliary nozzle.
